Now, there are many of these out there in the world,
and they are really freaking cool. But this one is
even cooler because you can take the plans and make
it yourself. And then you can make a 3d sex doll...
Or whatever...

Excerpt:

"Hod Lipson didn’t set out to revolutionize
manufacturing. He just wanted to design a really
cool robot, one that could “evolve” by
reprogramming itself and would also produce its own
hardware—a software brain, if you will, with the
ability to create a body. To do this, Lipson
(below, center) needed a rapid-prototyping
fabrication, or “fabber.” Picture a 3D inkjet
printer that deposits droplets of plastic, layer by
layer, gradually building up an object of any
shape. Fabbers have been around for two decades,
but they’ve always been the pricey playthings of
high-tech labs—and could only use a single
material."

I'm not entirely sure why, but this is one thing I
just must own. It's a little something researchers at
USC have cooked up, and it's pretty kickass. It
displays a true 360 degree viewable hologram. This is
very different from the holograms you may have seen
previously (even holographic video), because they are
usually only viewable from about 20 degrees. This one
works from the top, any side, bottom, you name it.
Finally one of those things we were promised from the
future. Just don't stick your hands in the spinning
mirror kids!
